Chemistry deals with phenomena that affect nearly every aspect of our lives and environment. A liberal education in this scientific and technological age should include some exposure to the theories, laws, applications, and potential of this science.

The chemistry curriculum is sufficiently flexible to allow students with career interests in areas such as the health professions, law, business, and education to design a major program suitable to their goals. Students interested in careers in chemistry or biochemistry will find sufficient chemistry electives to provide a strong background for graduate work, industry, or other positions requiring an in-depth foundation in chemistry. A major in biological chemistry has been developed in conjunction with the biology department. See separate listing under Biological Chemistry for more details. The department and its curriculum are approved by the American Chemical Society.

Cross-listed Courses. Note that unless otherwise specified, when a department/program references a course or unit in the department/program, it includes courses and units cross-listed with the department/program.

Major Requirements. All students majoring in chemistry are required to meet the following minimum course requirements: Chemistry 107A or Chemistry/Environmental Studies 107B; Chemistry 108A or Chemistry/Environmental Studies 108B; Chemistry 203; 212; 215; 217-218; 301; either Chemistry 302 or 310; 332; two upper-level chemistry electives or one upper-level chemistry elective with a laboratory; and Chemistry 457 or 458. Further course and unit selections depend upon the goals and interests of the student. All students preparing for graduate study or for a position in the chemical industry should include in their programs Chemistry 223, 316, and any other advanced courses in their specific area of interest. It should be noted that courses in mathematics and physics are prerequisites for some of the advanced courses in chemistry. A written thesis is required of all majors. This may be either a laboratory or library thesis. Students doing a laboratory thesis may register for Chemistry 457, 458, or both, while students doing a library project may register for Chemistry 457 or 458. Students in the Honors Program must register for 457 and 458. All senior majors must participate in the department's seminar program. Each major is required to deliver two research presentations during the senior year.

Pass/Fail Grading Option. Pass/fail grading may not be elected for courses applied toward the major.
